由于他们是客户端错误，您必须将它们发送到服务器使用XMLHttpRequest。您可以使用 try ... catch 语句或 window.onerror ：

Since they're client-side errors, you'll have to send them to the server using XMLHttpRequest. You could use try...catch statements or window.onerror:

window.onerror = function (msg, url, line)
{
    var message = "Error in "+url+" on line "+line+": "+msg;
    $.post("logerror.aspx", { "msg" : message }); 
}

注意行和 url 可能在8之前的IE版本中非常不准确。

Be aware that line and url can be very inaccurate in IE versions prior to 8.
